Yep, the LED's seem to absorb most of the power. I need 5V though, cause the pressure sensor requires 5V. Keeping the sensor and PIC A/D ref at the same voltage level seemed a clean, easy way to avoid unnecessary errors sources, and keep parts-count low. Not sure if it was the same project -- last major discussion I started was the automatic bathtub controller, and prior to that it was the 7-segment LED experiment. So many ideas, so little time... ----- Original Message ----- From: "Dal Wheeler" To: Sent: Wednesday, April 03, 2002 7:44 PM Subject: Re: [PIC]:Re: 7805 heating up... > Looks like the bulk of your power budget might be in lighting up the LED's. > If you're running them off the 5 v rail now, you might save some heat > trouble by driving them off 12v (or a seperate regulator (7808) if worried > about stable light intensity.) --I'm getting deja vu -is this the same > project discussed a few weeks ago? > > -Dal > > ----- Original Message ----- > From: Pic Dude > > > > Not in its current location -- only metal in the area is the stereo just > > below it, and I don't want to mess with that.
